1001 Video GamesDead or Alive 4 appears in the book 1001 Video Games You Must Play Before You Die by General Editor Tony Mott.
NicoleOne of the new characters available in the game is Nicole, a female Spartan from the Halo games. Her inclusion in Dead or Alive 4 is the result of a joint collaboration between Team Ninja and Bungie Studios, creators of the Halo franchise.
Interestingly enough, Bungie denied Team Ninja use of the Master Chief himself, and instead created Nicole and somehow made her story canon, as she's trapped in a time-bubble that keeps her in the 21st century and puts her in the way of the Dead or Alive tournament... Whether this is implies some future plans for Bungie's runaway Spartan or was simply just for fun remains to be seen.
